2020 300RR oil consumption

[jeff4880]

I just purchased a 2020 300RR and after approximately 6 hours of use the bike has used very little oil (if any) out of the tank. I've been riding mostly single track with it so speeds have been low but I'm still wondering if this is normal? Is there a way to confirm the OI is working?

can you see oil in the hose? Are there any bubbles? Any indicator lights? How much did the oil level drop in tank?

The safest way to check is to fill the fuel and oil tanks to a known lever and then measure fuel and oil used after a ride. You can then calculate the effective oil ratio.

As oil pump delivery is driven by throttle opening, don't be surprised if you find the ratio to be up to 90:1 if you have been running at low throttle openings.

If you prefer to test the oil delivery rate in the workshop, do the following:

Carefully remove the oil feed tube from the inlet manifold.
Block the oil inlet fitting on the manifold to stop it sucking air.
Empty the tank and put some premix in temporarily.
Start the engine and measure the amount of oil that is pumped on tickover. You should be able to see the oil pump pulses, especially if you hold the tube slightly up.

The oil pump delivers 0.007cc per stroke and it should take around 360 seconds to deliver 2.5cc of oil at 1 pulse per second. 2.5cc is 1 teaspoon, ask your local pharmacy for a medication measuring spoon or cup as these are really good for measuring small volumes.

Normal tickover rate is 1 pulse every 2 seconds, rising as the throttle is opened.

i noticed oil consumption on my 2019 XTrainer 300 varies HUGELY depends on how i ride.
it barely consumes very little oil for my style of riding which is tight single tracks mostly in 3rd gear and lower rpm and low throttle opening,
on the other hand, riding on the street, fire roads, rail beds or fast open trails it consumes much more.
